8' Claims.

This invention relates to a novel construction of carton or receptacleespecially adapted to enclose incandescent lamp bulbs, radio tubes, orother articles for commercial distribution and handling.

The invention has for an object to provide a carton or receptacle, thebody of which is made of a single piece or blank of sheet materialcapable of being rolled into substantially cylindrical form, the samehaving self-contained locking features for securing it in such form,ready for service, without necessity for the use of glue, staples orother independent fastening means; the form and arrangement of the novelcarton or receptacle being such that a plurality thereof will compactlypack together in larger, quantity containers.

The invention has for another object to provide cartons or receptacles,of the kind mentioned, equipped with means which not only support theenclosed lamps, etc., subject to testing without necessity for theremoval of the latter therefrom, but also being adapted to adequatelyreenforce the carton or receptacle bodies against crushing or collapsingstresses, thereby protecting the lamps, etc. against injury; means alsobeing provided which permits visualization of light from the lamps whenthelatter are tested.

- The invention has for a further object to provide cartons orreceptacles adapted, when so desired, for the display of the contentthereof; means being also provided for supporting the carton orreceptacle bodies upon a counter or for suspending the same, as may beelected; and means being further provided whereby convenient' display ofadvertising matter in connection with each carton or receptacle isattained, said latter means serving also as further reenforcement forthe carton or receptacle bodies, when the latter are stored or packedtogether.

Other objects of this invention, not at this time more particularlyenumerated, will appear in the following detailed description of thesame.

Illustrative embodiments of the invention are shown in the accompanyingdrawings, in which:

is a bottom plan View, with the easel or prop portion folded down.

Fig. 9 is a plan view of a blank form which is made of the carton orreceptacle, in the form shown by Figs. 1 to 8 inclusive.

Fig. 10 is a plan View of a blank from which 5 is made a modified formof the carton or receptacle; Fig. 11 shows a carton made from the blankof Fig. 10 as opened up for display of its content and associatedexplanatory or advertising matter; and Fig. 12 is a back view of thesame. 10

Similar characters of reference are employed in the above describedviews, to indicate corresponding parts.

Referring to Figs. 1 to 8 inclusive, the form of carton or receptacletherein shown is made from a blank such as shown in Fig. 9. This blankis cut or died out from a suitable sheet material, such e. g. as paper,cardboard or like suitably flexible material; and the parts thereofhereinafter described are preferably, although not essentially,integral. The blank comprises a main section I having, parallel to andspaced from one end 2 thereof, a transverse slot 3 of less length thanthe width of said section I. Said slot 3 divides said section I into acarton body portion 4 extending above slot 3, and an easel or propportion 5 extending below slot 3. Extending longitudinally and centrallyfrom the opposite end 6 of said main section I, and thus projecting fromthe carton body portion 4, is an external panel portion 1 of reducedWidth. Formed in connection with said panel portion 1, adjacent to itsjuncture with said carton body portion 4 from which it projects, arelaterally and oppositely projecting lock tongues 8, the free endportions of which are separated from said body portion t by inwardlyextending slits 9. The distance between the free extremities of saidoppositely projecting lock tongues 8 is in excess of the length of slot3, but the distance between the inner ends of slits 9 is somewhat lessthan the length of slot 3. Cut out of the carton body portion i, at asuitable location between its sides and intermediate end 6 and slot 3,is a window opening til. 45

Toform the novel carton from the above described blank, said blank isturned endwise upon itself and the free end of panel portion 7 isthreaded and drawn through said slot 3, and by suitable lateral shiftingoperations lock tongues 8 are also passed through the slot 3 to theexterior side of body portion 4, whereupon the slits 9 will embrace thematerial beyond the ends of the slot 3. By this manipulation, bodyportion 4 is rolled into an open ended cylindrical carton body, themeeting ends of the body portion t being interlocked against separationby the engagement of the lock tongues 8 through slot 3 (see Fig. 8),thus retaining the body portion in the aforesaid cylindrical shape.Panel portion 1 is thereupon wound externally around the cylindricalcarton body thus obtained, and its free end portion is again insertedthrough slot 3 (see Figs. 2 and 4) to thereby retain said panel portionin enveloping relation to the carton body t in which position it notonly aids in reenforcing and strengthening the body portion 4, but alsoserves as a cover for window opening 10.

In the drawings, the novel carton or receptacle is shown supplied with acontent comprising two incandescent electric lamp bulbs H, although itwill be obvious that the carton or receptacle is equally adapted toenclose but a single bulb, radiobulb or other article adapted forinsertion and support therein. When employing the carton to enclose thetwo bulbs H, a center disk l2 of comparatively heaw cardboard, or of anyother relatively rigid material, is inserted within the carton interiorto extend transversely across such interior midway between the cartonends. The perimeter of said disk 52 frictionally engages the inner wallsurfaces of the cylindrical carton body 4, so that the same is therebyheld in place. Said disk [2 not only reenforces and supports the cartonbody walls against crushing or collapsing stresses, but also forms alight impervious partition between the enclosed lamps ll; an advantagethe desirability of which will later be referred to. Adapted forinsertion within the respective open ends of the cylindrical carton body4 are end disks l3. These end disks iii are likewise made ofcomparatively heavy cardboard or other relatively rigid material, andare transversely disposed with their perimeters frictionally engagingthe inner wall surfaces of the cylindrical carton body 4, whereby thesame are held in place and also serve to further reenforce and supportthe carton body walls against crushing or collapsing stresses. Said enddisks l3 are provided with central perforations or openings l4 sized toreceive therethrough and frictionally enage the base portions 15 of thelamp bulbs ll, whereby not only are the lamps firmly supported withinthe carton interior, but the contacts l6 thereof, which are carried atthe ends of said base portions l5, are exteriorly exposed through theopen ends of the carton body, and thus are accessible 'for engagement,through said open ends, by the terminals of a suitable lamp testingmeans. Said panel portion 1 is provided with suitably disposed smallports or openings ll which, when the panel portion is arranged ininitial enveloping relation around the carton body 4, and across thewindow opening ll] of the latter, are adapted to register over saidwindow opening respectively at points on opposite sides of said centralpartition disk [2, so that when either lamp is tested, the light emittedtherefrom may be seen through a corresponding port or opening I1. Owingto the presence of the central light impervious partition disk, when agiven lamp is tested the light emitted therefrom cannot gain access tothe enclosure containing the other lamp, and consequently testing errorsare easily avoided, and each lamp may be independently tested withoutconfusing one with the other.

When the novel cartons are to be assembled in quantity to be packed in alarge quantity container, or to be stored, as on a store shelf, theeasel or prop portion 5 and the free end of .panel portion 1 may befolded contiguous to the exterior surface of the cylindrical cartonbody, and consequently compact assembly of the cartons in groups orpiles is easily accomplished. When a single carton is removed and laidon a counter, it will not roll, with risk of falling and consequentinjury to the lamps contained therein, since, when free of restraint,said easel or prop portion 5, and said free end of said panel portion "Iwill project in such manner as to form a more or less flat footing orbase for the stationary support of the carton (see Figs. 2 and 4).

If it is desired to utilize a carton for displaying the contained lamps,and also for displaying explanatory or advertising matter in connectiontherewith, the panel portion 1 is disengaged from slot 3, and the sameis unwound from enveloping relation to the carton body exterior, and isextended lengthwise in upstanding position, as shown in Figs. 6 and '7,and at the same time easel or prop portion 5 is outswung to operativeposition (see Fig. 7), so that the carton is supported against rolling,while the panel por tion extends upwardly behind the same. When thecarton is thus disposed, its window opening ID will be uncovered toexpose the interiorly disposed lamps H to view, and, at the same time,any explanatory or advertising matter printed upon the inner surface ofpanel portion 1 will likewise be exposed to view. In some cases, insteadof thus standing the carton on a counter, show-case top or like place ofsupport, it may be desired to suspend the same against a wall or insimilar disposition. To allow this, a suspension perforation i8 isprovided in panel portion 1 adjacent to its free end which may beengaged over a hook, peg or other suitable means of suspension support.

In Figs. 11 and 12 there is shown a somewhat modified form of the novelcarton or receptacle, the arrangement of which is such as to provide alarger area of advertising display space. This modified form of thecarton receptacle is produced from the blank of suitable sheet materialshown in Fig. 10. This blank comprises a body portion 20 and an externalpanel portion 21 extending therefrom, a transverse slot 22 beingprovided between said body and panel. Extending from the free end ofsaid body portion 20 is an easel or prop portion 23, in connection withwhich are formed, adjacent to its juncture with said body end,oppositely projecting lock tongues 2c. The body is provided with asuitably disposed Window opening 25, and the panel with the sightopenings 26 and suspension opening 2?, if desired. In the formation ofthe carton or receptacle from the thus modified blank, the body isrolled into cylindrical form in such manner that the easel or propportion 23 and lock tongues 2 3 may be passed through slot 22, therebylocking the body in the desired tubular cylindrical form. The lamps I iand reenforcing partition and holding disks l2 and [3 are inserted inthe formed body 26 in the same manner and relations already abovedescribed. The panel 2| may be initially wrapped around the body 20 andits free end tucked beneath the easel or prop 23; when it is desired touse the carton for display purposes, said panel portion 2! may beunfolded and erected, and the easel or prop extended as shown in Figs.11 and 12. It will be noted that, in this modified arrangement, thepanel 2| furnishes a considerably enlarged area of advertising space.

It will be obvious that various modifications of arrangement and shapeof the-parts, other than those above mentioned by way of illustration,may be made within the spirit and scope of this invention; and, in fact,many apparently widely different embodiments of this invention could bemade without departing'from the scope thereof as defined by thefollowingclaims.
